I'm throttled by AT&T. And My iPhone is pretty much useless. Can't send texts, either SMS or iMessage. Can't use maps, well I mean, maps finds me via GPS but with no data connection it can't map where I am. Can't run speedtests (stuck on "Finding Closest Server") Can't get e-mail. To make matters worse, I "used" to be able to get wifi reliably in my office with my iPhone4. Not so with the 5, if i get any wi-fi it cuts out sporadically. I guess I didn't know that because my wi-fi is so crappy I was using lots of LTE. Oh and I don't know how I used 8GB of LTE when they "throttle" you after 5gb. There's no way I've been able to eat up 3gb of data at .45Mbps.
